Abstract
The surface of a LB film of polyamic acid long alkyl amine salts, cons isted of a mixture of aromatic and aliphatic polyamic acids, was obser ved by means of friction force microscopy (FFM). The LB film having 11 layers gave no significant pattern by atomic force microscopy (AFM), whereas clearly phase separated morphology was observed by using FFM.
